The answer is: There are 595 calories in a banana split
To find this we first need to set up our equation:
\(80= \frac{1}{7}x-5\), where x= calories in a banana split
\(85= \frac{1}{7}x\)----------------Add 5 to both sides
595=x-------------------Multiply 7 to both sides to get rid of the fraction
So, there are 595 calories in a banana split
Hope this helps! :)
